Is a network security device, either hardware- or software-based, that monitors and controls incoming and outgoing network traffic based on a set of security rules in order to protect internal private networks from unauthorized access, malicious attacks, or intrusions.
A detector that is intended to sense a flame.
A specially designed switch with connections for inputs from multiple flame detectors. The switch has a built in logic to determine the presence of a flame based on these inputs.
A physical object that is a projecting flat rim, plate, collar or rib.
A system that burns waste in an elevated flame in the open air.
A burner that burns gas emitted from a process into the atmosphere.
An analysing instrument intended to determine the flash point of a substance.
A flexible vertical or near vertical pipe for the flow of liquid or gas between the seabed and the surface.
is a process unit with gentle agitation used to bring together fine particulates in wastewater into larger clumps or flocs through physical contact to enhance the subsequent separation and removal of solids in sedimentation basins.
A detecting element that is producing a signal that is proportional to a flow rate.
A gauge intended to indicate a liquid or gas flow.
A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.
A functional switch that is intended to give a signal when the flow have reached a pre-set value.
A totalizer that adds up flow measurements.
A flow transmitter providing an output signal that is proportional to the flow inputs from a flow element.
A device capable of detecting droplets of water vapour suspended in the air near the ground.
An analyser intended to determine the freezing point of a liquid.
A device that generates an electrical signal of a specified frequency.
A signal converter that is intended to convert a frequency or rotational speed input signal into a 0 - 20 mA or 4 - 20 mA current output signal.
A hollow cone with a tube extending from the smaller end and that is designed to catch and direct a downward flow.
A physical object that is intended to induce a reaction in a process fluid by heating it.
A chromatograph where gas is injected directly into one or more separation columns.
An analyser which analyses the composition of gaseous mixture with two or more components.
A detector that is intended to sense the presence of a specified concentration of a gas.
A chromatograph where a liquid sample is injected and evaporated and subsequently carried to one or more separation columns.
